Raid 1/0 SSD vs 2 x non-Raid SSD [closed]

http://serverfault.com –
I have a question about speed performance with two separate SSD drives comparing them to RAID mirror array. I do not like idea to setup RAID 0 with 2 x SSD drives because of high risk of data loss, but I like an idea to have read speed advantages from RAID 1 array.
So what if I will set 2 x SSDs separately: one is for /www resources another just for /mysql DB that accessing same time.
Could I expect same speed increment as for RAID 1?
